MACHINE FOR APPLYING FASTENERS AND BAILS TO PAPER VESSELS.

Application filed June 26, 1908.

plying Fasteners and Bails to Paper Vessels, of which the following is a specification.

My invention relates to machines for applying or attaching the fasteners and bails to paper vessels, such as oyster pails and the like, and the object thereof is to provide a novel and efficient machine of this character capable of applying such fasteners and bails with great facility and in a an automatic manner. The machine so produced by me is capable of forming the fasteners and bails and of applying them in a single operation, such machine being also capable of clenching the ends of the bail between the folds of paper of the pail, as for instance between the usual corner folds and the side walls of the pail, so that the inner walls of the pail will not be perforated and such clenched ends will not be exposed on the inside of the pail and will not therefore interfere with the nesting or stacking of the empty pails.

My machine is, in the present instance designed to cut off the fasteners from continuous strips properly punched and to form the bails from a continuous length of wire and to automatically apply or attach such fasteners and bails to the pail.

Other novel and advantageous features of construction and operation will be apparent from the description hereinafter given.

In the drawings, Figure 1 is a front ele vation of my machine, with the exception of the base portion or support which rests on the floor; Fig. 2 a section on line 2-2 of Fig. 1; Fig. 3 a sectional'plan view on the line 3-3 of Fig. 1, but on an enlarged scale;

Although my machine may be employed for applying or attaching the fasteners or so-oalled tins, (owing to the fact that they are made of that material) and also applying or attaching the bails to paper vessels generally, yet in the present instance my machine is adapted and designed for attaching such fasteners and bails to that class of paper vessels commonly known as oyster pails or buckets, and I will now proceed to describe my invention in connection with a machine adapted for this specific purpose without intention of limiting myself to the particular character of paper vessel operated on.

The particular type of oyster pails herein operated on is illustrated in Figs. 12 and 13, having the usual four side walls A and corner folds a which are folded over upon two opposite side walls. Such pail has the usual covers or lids a hinged to two opposite side walls and also the usualextensions a hinged to the upper edges of the corner folds, through which the ends of the bail are passed and to which the fasteners are applied. Oyster pails of this general character are formed from blanks made by machines constructed for this purpose; and in the present instance I contemplate taking the pail blanks as they come from a machine of this general character and by feeding them to my present machine, applying or attaching the fasteners and bails thereto, as the last step in the manufacture of the pails.

My machine, as herein shown, is adapted to automatically cut off the fasteners and the wire from continuous lengths which are wound upon reels and the like, and to attach or apply the same to the pail in a single operation. Speaking in general terms, the oyster pail which has been previously creased so that it may be folded to proper form is placed in substantially flat form in the ma chine and, in order to be operated upon by the mechanism, it is brought to proper position by means of a plunger or block corre sponding to the interior dimensions of the pail, in which operation the pail is auto matically folded from flat form to its proper or assembled form and held in such assembled form until the fasteners and bail have been attached, whereupon the completed pail is ejected from the machine which is now ready for the next pail and so on. The fasteners before being attached are severed from their respective strips, there being two differently shaped parts to these fasteners as is well known, after which said fasteners are applied to the pail and clenched thereto against said plunger or block. At substantially the same time, the bail is cut from a continuous length of wire and properly formed and subsequently attached to the pail, 'the ends thereof being forced through the so-called corner folds only of the pail and clenched against special stationary anvils, which enter between said corner folds and the outer faces of two of the opposite side walls when the pail is moved downwardly by said plunger or block, as described, with the result that the ends of the bail are clenched against the inner faces of said corner folds and not against the inner faces of the side walls, so that such clenched ends of the bail are not only concealed, but covered so as to prevent anything catching thereon and also as not to interfere with the stacking or nesting of the pails.

Referring to the embodiment of my invention as herein shown, the machine is provided with a main frame in which the different working parts are mounted and which comprises more particularly the vertical standards 1 carrying the operating mechanism at their upper ends, and a bed plate 2 on which the fastenenattaching and the bail-forming and applying mechanisms are mounted to operate. The power shaft 3, suitably driven as by means of a pulley 4: from any source of power, is journaled in the main frame and provided with a pinion 5 meshing with a gear 6 secured to a hori zontal shaft 7 journaled in the upper ends of said standards. This shaft 7 is provided at its opposite ends with two cam wheels 8 and 9 which are adapted to reciprocate the two vertical rods or bars 10 and 11, respectively, through the medium of the cam rollers 12 and 13, which rods or bars are operatively connected, in a manner hereinafter described, with the fastener-attaching mechanism. The shaft 7 is provided at its extreme right-hand end (Fig. 1) with a third cam wheel 1-1, adapted to reciprocate a vertical rod or bar 15, through the medium of a cam roller 16. This rod 15 is operatively connected to the wire feed mechanism, as hereinafter described, for feeding the wire from a reel to the machine. The shaft 7 is provided with a fourth cam wheel 17 which is adapted to reciprocate a vertical plunger 18 through the medium of a cam roller 19. This plunger is guided in its vertical move ments in suitable manner as by means of a cross piece 20, which extends between the standards 1, and through which such plunger passes. Upon the lower end of this plunger is secured in suitable manner a metallic block or anvil 21 substantially corresponding in form to the interior of the pail and therefore having four sides partaking generally of the form of the body of the pail and vertical or straight portions partaking of the form of the extensions or covers of the pail. However, as illustrated in Figs. 2 and 2, two of the opposite sides of the plunger are practically flat and provided with pairs of parallel corner flanges 21 the purpose of which will be hereinafter made apparent. Upon this plunger the pail is held in its assembled condition in position to be operated upon by the machine, such plunger also forming an anvil against which the fasteners are clenched, special anvils being provided for clenching the ends of the bail, as hereinafter described. As illustrated in Figs. 1, 2 and l, and in detail in Fig. 11, a false plate 22 is held projected from the lower end of this plunger with a yielding pressure, in the present instance such plate having an upward extension or stem 23 fitting within a bore or chamber extending upwardly from the lower end of the block. This stem has a pin-and-slot connection 24; for holding it in place within the plunger and for limiting the outward movement to which it is subjected by the coiled spring 25 pressing against its upper end. The plate 22 corresponds exactly to the inner dimensions of the bottom of the pail and is adapted to bear thereagainst and press the entire box downwardly until the bottom of the box strikes against the upwardly spring-pressed plate or plunger 26 which is guided in a suitable frame 27 depending from the base plate of the ma chine. When in said downward movement of the plate 22, the tension of its spring 25 is overcome, the plunger 21 will continue to move downwardly and after striking said plate 22 will force the latter, together with the plunger 26 downwardly until it is stopped by the abutment which is in the form of an adjusting screw 28, whereby the relative position of the pail with respect to the mechanism may be accurately adjusted. In the present instance the plunger 26 is normally held upwardly by means of the coiled spring 29.

In order to properly form or fold the previously creased or scored blank of paper into the form of a pail, by the action of the plunger 21, I provide suitable means which, for

convenience, I term, as a whole, a former because of its function of thus forming or bringing the blank to the form of a pail. This former in the present instance comprises blocks and wire guide frames and also spring-pressed plates, which when asse1nbled, form an upwardly and outwardly flaring opening upon the top of which the paper blank is laid and down into which it is pressed and caused to assemble to the pail form by the described action of the plunger 21. Moreover, the pail is maintained thereby in its assembled or erect form until and during the action of the mechanism for attachir g the fasteners and the bail.

As clearly shown in Figs. 3, 4, 5 and 15, the blocks referred to and indicated at 30 are in pairs at opposite ends of the opening, the same being properly curved or flared to assist in the folding of the pail, and are provided with wire frames 31 preferably shaped as'indicated inFigs. 3 and 4, the ends thereof being inserted and held in holes provided in said blocks, and the intermediate portion being supported at the upper end of parallel extensions 32 which project upwardly from the blocks. The ends of the opening of the former are formed by means of a pair of plates 33 located between said extensions 32 and held inwardly with a yielding pressure in suitable manner, as by means of the pairs of rods 34 secured to the outer sides thereof and spring-pressed by means of the coiled springs 35. These rods pass through brackets 36 mounted at the outer ends of projections or studs 37, extending laterally from the blocks 30. These rods, being screw-threaded into their brackets, may be adjusted as desired. The blocks are, in the present instance, mounted upon the removable plates 38 and 39, respectively, which are adapted to slide above the bed of the machine and beneath the guide plates or strips 40, Figs. 3 and 4, with the result that said plates, together with the pail forming or assembling mechanism described, may be removed for any purpose from opposite sides of the machine.

The fastener to be applied to a paper vessel like an oyster pail consists of two parts, one an eye portion or fastener proper indicated at B in Fig. 7, and a tongue portion indicated at C in Fig. 9, the same being applied to opposite sides ofthe pail and the tongue being inserted through the slot or eye in the fastener proper and bent tliereover to fasten the covers of the pail in place. As stated, these parts of the fastener are in long strips on reels 41 and 42, Fig. 1, the strips being previously punched as shown in Figs. 7 and 9, but left fastened together in a continuous strip and subsequently sheared off, one by one, as needed in the machine. These strips are supplied to the machine on opposite sides of the opening of the former which receives the pail and are applied to said pail automatically by the mechanisms about to be described. These two mechanisms are similar in general construction and operation, but differ slightly in proportion, owing to the fact that the tongue portion of the fastener is longer than the eye portion thereof.

Describing the mechanism for applying the eye portion B of the fastener, a bar is mounted to reciprocate in a stationary guide frame 44 arranged on the lefthand side (Fig. 1) of the former for the pail and at right angles thereto, as clearly indicated in Figs. 1, 3, 4 and This bar is operated by means of the vertically reciprocating rod 10 hereinbefore described, the operating connections being a link 45 secured to said rod 10, a bell-crank 46 pivoted to a bracket 47 on the main frame, and an adjustable rod connection 48, which is pivctally connected to the outer end of said reciprocating bar. The strip of fasteners B is taken from the reel 41, as shown in Fig. 1, and fed upwardly through a curved guideway or channel 49 extending upwardly through the bed plate of the machine so as to present a fastener in position in advance of the inner end of said reciprocating bar 43, as indicated in For the purpose of feeding this strip automatically and at the proper time, I provide, in the present instance, a rocking arm or lever 50 stationarily pivoted at its outer end at 51 and at an intermediate portion to the lower ends of a pair of vertically recipro cating plates 52 mounted to slide in the guide frame 44 adjacent opposite sides or faces of the reciprocating bar 43.

Each plate is provided on its inner face with a lateral lug or extension 53 of the peculiar shape clearly illustrated in Fig. 5, so as to cooperate with the angular slot or groove 54 formed in one side of the reciproeating bar and adapted to receive said projection 53. It will be understood that as the bar 43 is reciprocated the plates 52 will be moved vertically. As shown, said groove is straight and horizontal as to its outer portion, but angular at its inner portion, with. the result that when the reciprocating bar 43 is in its outward position, as indicated in Fig. 5 said projections 58 will occupy the angular front portion of the groove, whereupon the plates 52 will be in their uppermost position, raising the arm 50 to its upward limit of movement. As the bar 43 is advanced inwardly in the fastener-attaching operation, said projections 53 will be forced downwardly and will occupy a position in the horizontal portion of said groove, with the result that said plates 52 will be moved downwardly. The object of this movement of the plates 52 is to reciprocate the inner end of the arm 50, which acts to feed the strip B upwardly at the proper time. For this purpose, said inner end of the arm 50 is provided with a spring-pressed pawl 55 pivoted thereto and having an inwardly extending tooth 56. This tooth extends into said channe14t9 and on its upward movement is adapted to engage the strip B and feed the same to the machine. In the downward movement of said arm 50 said tooth obviously rides over said strip without engaging the same, but in order to prevent backward or downward movement of the strip suitable means may be provided, as for instance, the locking pawl or dog 57 which engages said strip and permits upward movement only thereof. As stated, the strip B is fed into the channel of the guide frame, in which the reciprocating bar 43 slides and the same is introduced in advance thereof, as shown in Fig. 5. In this introduction of the strip, just enough thereof is fed to provide a single fastener, that is the eye portion of the fastener, so that the division line between two of such fasteners on the same strip coincides exactly with the top surface of the plate 58, on which said bar slides. In order to automatically shear such fastener from the strip, I provide on the lower inner corner of the reciprocating bar a knife edge 59 which cooperates with a knife edge 60 on the inner side of the opening 61, through which the strip is introduced. It will be understood that as the bar 43 is advanced inwardly, a fastener will be cut off from the strip. However, provision is made for engaging and holding the fastener on the inner end of the bar 48 just before the fastener is severed from its strip so that such bar will carry the fastener inwardly and in a proper position to be attached to the pail. These engaging and holding means comprise, in the present instance, a spring-pressed pin 62 projecting forwardly from the inner end of the bar as, as clearly shown in Fig. 5, and in position when advanced inwardly with its bar 43, to enter one of the holes 5 previously punched in the strip B and intended for clenching said fastener to the pail. Such means also comprise an arm 63 shown in detail in Fig. 8 and having at its lower or inward end parallel flanges or shoe portions 64, which are adapted to slide in recesses 65 in the reciprocating bar 43. This shoe is adapted to fit over the upper end of the fastener B, as indicated in Fig. 7, to hold the same in proper position or alinement for presentation and attachment to the pail. This shoe is arranged to move inwardly in unison with the reciprocating bar 48, and to have an independent movement with respect thereto in the act of applying and clenching the fastener to the pail. To this end, the arm 63 has a pin-and-slot connection 66 with said bar 13 and is pivotally connected at its outer end to a rod 67, which has a bearing 68 and is spring-pressed inwardly by means.

of the coiled spring 69, all as clearly indicated in Fig. 5. It is now obvious that when the reciprocating bar 43 is moved inwardly the fastener will enter within the shoe and immediately thereafter the pin 62 will enter the opening or hole b in the fastener, after which the fastener will be cut off from its strip. The fastener is now engaged and held by the forward end of the reciprocating bar 43 and is advanced inwardly toward the pail in the inward movement of said bar. At the innermost limit of movement of said bar, as indicated in F ig; 11, the fastener is attached and clenched to the extensions a of the pail, in which operation the inwardly extending flanges of such fastener formed in the act of punching the series of three round holes, are forced through said extensions a and against the clenching surface 70 on one side of the block 21, Fig. 11. When the reciprocating bar is thus advanced the shoe 64 will yield, that is, will become stationary when its forward end strikes the block 21, leaving the bar 43 to continue its inward movement and attach the fastener. As the reciprocating bar 43 was thus advanced, the plate 52 was moved downwardly, inasmuch as the projection 53 thereof was forced from a position in the angular portion in the groove 54, to a position in the horizontal portion thereof, as indicated in Fig. 11. Asa result, the inner end of the arm 50 was rocked downwardly to the position indicated in Fi 11, so as to engage the strip A in a position to feed such strip upwardly a distance of one fastener. This completes a cycle of movement of this mechanism, the operation being continuous and in unison with the operation of the mechanism on the opposite side for attaching the tongue and als in unison with the operation of the bail-forming and applying mechanism, hereinafter described.

The mechanism for applying or attachinn the tongues is located on the right-hand side (Fig. 1) of the former which receives the pail, and the same is in alinement with the mechanism already described for attaching the eye portion of the fastener. Inasmuch as the mechanism is substantially the same in construction and operation as the fastener-attaching mechanism already described, it will be unnecessary to make a separate detail description thereof, but sufficient to apply the same reference characters, but primed, to the corresponding parts. However, instead of the shoe 6%, a second spring-pressed pin 71 similar to the pin 62 which engages the lower hole 0 in the tongue portion of the fastener, is provided to engage the upper hole 0 thereof, with the resuit that these two pins engage and carry the tongue portion of the fastener inwardly in position to be attached and clenched to the pail. It will be understood, of course, that the reciprocating bar 43 is somewhat higher than the other bar 43 in order to provide for a longer angular portion to the groove 54, inasmuch as, owing to the greater length of each tongue portion of the fastener a greater are of movement must be imparted to the oscillating arm 50. The bar 48 is operatively connected to its vertically reciprocating driving rod 11 by a series of connections similar to those on the other side of the machine and therefore similarly lettered, but primed.

The mechanism above described for attaching or applying the fasteners to the pail are intended to act upon the pail substantially simultaneously with the mechanism for forming and attaching the bail thereto, although the first-named mechanism may be employed alone for merely attaching fasteners to a pail or other paper vessel. The mechanism for forming and applying the bail to the pail is of the same general character as the corresponding mechanism illustrated in my prior Patent No. 537,640, dated April 16, 1895, but my present construction embodies certain modifications or changes, as well as additional features which are of utility and advantage in a machine of this character.

My present construction of bail-forming and applying mechanism which is illustrated in general in Fig. 3, and in detail in Fi s. 14 to 22, will now be described. The

bail mechanism about to be described is adapted to cut bail len ths from a continuous wire, to shape the bail length into the form of a bail. and to drive and clench the free ends of the bail in the pail. In the present instance, I provide for the driving of the bail throu h the corner folds only of the pail and the clenching of the same upon the inner faces of such corner folds, with the result that the two adiacent side walls are not perforated as is usually the case in pa er vessels of this character, but are left entire or unbr ren. The means or mechanism whereby this clenching is done in this manner forms one of the principal features of m invention. Referring particularly to Fi 3. the bail mechanism is principall located behind the mechanism-for attaching the fasteners and has a reciprocating movement toward and away from the pail in said last-named mechanism.

As shown in detail in Figs. 14, 15 and 16., a main slide frame 72 is, provided on which the bail mechanism proper is adapted to slide and to be guided in its reciprocating movements. In the present instance, and

as a matter of mechanical convenience, this frame plate 72 is made of a special piece of metal which, instead of being attached at its sides to the main frame, is placed between and supported by two stationary side plates 73 attached to opposite sides of the main frame, all as clearly illustrated in Figs. 15 and 16. This frame plate 72 is provided on its upper face with a series of ribs and grooves which are complementary to ribs and grooves on the underside or face of a reciprocating slide plate 74, which is U- shaped in general outline, as indicated more clearly in Fig. 1-1, the central front portion of such plate being provided with a rectangular opening to accommodate the pailformer and permit the two parallel members of'said slide frame to pass beyond the plane of said former and on either side thereof. as hereinafter made apparent. This slide plate is reciprocated in any suitable manner, but in the present instance, as shown more particularly in Figs. 2, 3. 14 and 17, the same is operated by means of an upright lever 75. operatively connected at its lower end to the cross bolt 76, which in turn is connected with the slide plate by means of the two parallel links 77. The lever 7 5 is rocked by means of a cam wheel 78 having a cam-way in which is positioned a cam roller 7 9 at the upper end of the lever 75. The cam wheel 78 is secured to the shaft 7 hereinbefore described and is properly timed in respect to the other mechanism. One of the forward ends or corners of the sli e plate is p ovided with a lrnife edge 80. Fig. 21. which in its forward reciprocation, is adapted to shear off a h il len th from a continuous len th of wire which is intermittently fed nto the machine by any suitable wire-feediw mechanism. such as that illustrated enerally by the reference character 81 in Fig. 1. Inasmuch as any suitable me hanism for this purpose ma be em lo ed, the same need not be described in detail. The wi e l) is fed by said mechanism trans ersely of the machine and through an opening or wire slot 82 in the main frame pl te 72. As set forth in my prior patent. this wire slot is inclined upwardl and f rwardly so that the bail wire after being fed into the machine may be raised in said slot to a pr per position to be operated upon by the a l mechanism.

As shown more pa ticularly in Figs. 14, 16, 21 and 22. each of the pa allel members or arms ofthe -U-shapedslide plate 74 is provided with a horizontal slot or channel 83 of a size to receive the two driving plates or hammers 84, Fig. 20, which are arranged to be carried by the slide plate and to therefore move with it, and to also have an independent movement transversely thereof so that at the end of the inward movement or reciprocation of the slide plate the hammer plates will be driven inwardly toward each other and against the ends of the bail to be clenched and thereby accomplish the clenching of the bail in cooperation with certain clenching plates hereinafter described. In order to cause this independent or transverse movement, the hammer plates are provided with upwardly extending projections or lugs 85, Figs. 16 and 20, which are arranged to travel in angular slots 86 of the two par allel stationary, but adjustable plates 87, which are mounted upon the main frame plate 7 2 and extend inwardly and partially over the slide plate 74, as clearly shown in Fig. 16. The rearward portion of the slots 86 are substantially straight but their forward ends are acutely angular, with the result that when the slide plate 74 is in such a position that the lugs 85 are in the straight portions of the slots, the hammer plates will be maintained in their outermost or normal positions, but that when the slide plate 74 is moved forwardly suiiiciently to present said lugs to the angular or front portions of said slots the hammer plates will be driven inwardly because of the clenching operation above referred to as hereinafter described in detail.

As shown in Figs. 20 to 22, the forward inner corner of each hammer plate is somewhat enlarged or extended, as shown at 88, in order to provide the curved shoulders 89 which serve to properly drive the ends of the bail and to accurately direct them in the clenching operation, as shown in Fig. 22. Immediately after the bail length is sheared from the len th of wire. the free ends of such bail length which are to be clenched, are bent at right angles in the manner indicated in Fig. 21. This result is accomplished by means of the forward extensions 90 of the slide plate 74, wh se forward ends so bend the wire ends against the outer sides of the ribs 91 of the main frame plate 72. These extensions of the slide plate are grooved at 92 so as to accommodate said wire ends in the further or continued movement of the slide plate 74, but immediately after these wire ends are thus bent. the bail length is elevated in its inclined slot by means of the sh es 93 which are clearly indicated in detail in Fig. 19. such shoes forming a portion of the slide plate itself and traveling in slots or guides in the main frame plate 72. Fig. 21. In order to guide the wire or bail length and to cause the same to enter the inclined slot or wire-way 94 of the slide plate 72, I provide a series of curved fingers 95 projecting forwardly and downwardly from said slide plate, as shown in Fig. 19. In this manner, the wire is raised and removed from the wire-way or slot in the main frame plate 72 and is carried or positioned in the wire-way or slot 94 of the slide plate, in order to be acted upon by the bail-shaping means now to be described. In the further forward movement of the slide plate the bail wire which is now at the upper end of the wire-way 94 is contacted by the forward inclined edge of the extensions 96 which project inwardly from opposite sides of the slide plate 74, and into the same channel or slot 83, in which the hammer plates are located. When these extensions 96 contact the wire, the latter will be bent at right angles to form the parallel arms or members of the bail, the middle portion of such bail being held in the wireway in a manner hereinafter explained. These extensions 96 are intended to give the bail its general formation, but in order to provide for acute angles between the bail handle and its arms, I provide that the inner corners 97 shall contact the outer ends of said arms and form said acute angles against the stationary portion or block 98. through which the bail handle passes. In order to accommodate the arms of the bail after being thus acted upon, the slide plate is provided with the slots 99 to accommodate such arms.

As hereinbefore stated, the bail handle passes through the block 98 which is located immediately behind the pail-former. As shown in Fig. 17, the wire-way 82, which extends transversely of this block, is inclined forwardly and upwardly, the forward wall thereof being the longer by reason of the ex tension 101at the forward edge of the block. However, such wire-way is provided at its rearward side with a pair of upwardly extending fingers 102, whose forward edges form practically a part of said wire-way. For the purpose of holding the bail handle rigidly in position while the bail is being shaped from the bail length, and while the ends thereof are being clenched. I provide means for clamping the bail and handle in the wire-way 100. In'the present instance, this clamping means consists of a reciprocating clam ing block 103 which is formed on or carried bv the front end of a slide 104, which is adapted to slide upon the main frame plate 72 and to be reciprocated in opposite directions by the slide plate 74, but having a less degree of movement than such slide plate. In the present instance. the slide plate is dove-tailed into the frame plate 72, Fig. 16, and has a bolt and slot connection with the sliding plate 74. As shown more particularly in Figs. 14 and 17, a screw bolt 105 extends downwardly through the rearward portion of the slide 104:. This screw bolt is secured to a shoe or follower 107, which is provided with two widths in cross section to correspond with the similar unequal widths of the slot 106. By these means, the slide 104: is held in operative relationship with the slide plate 7 1, and actuated thereby, but permitted to have independent movement. It will be understood that by reason of this bolt and slot connection, the slide 104; remains stationary during the greater portion of the forward movement of the slide plate 74, but that when the bolt contacts the forward end of the slot 106, the slide will be moved forwardly with the result that the forward end of the clamping block 103 will be forced against the handle portion of the bail which at this time is at its uppermost position in the wire-way 82 in the same horizontal plane as the clamping portion of the block 103. As a result, the bail is held at its handle portion in a rigid manner so that the other operations de scribed in respect to the bail may take place. In the rearward reciprocation of the slide plate, the slide 101 will remain stationary until the screw bolt has contacted the rearward end of the slot 106, whereupon the slide will be restored to its normal rearward position.

Now referring to the clenching mechanism and clenching operation more in detail, and referring more particularly to Figs. 11, 15, 17, 21 and 22, 1 provide a pair of clenching members or anvils 108 which are parallel to each other and arranged at opposite sides of the pail-former. As shown more particularly in Figs. 15 and 17, these anvils are secured at their lower ends only to the extenthat these anvils are stationary, and are so located with respect to the pailfo mer that when the pail is forced downwardly in the manner hereinbefore described, the latter will also be forced downwardly upon the anvils which will be located between the corner folds a and the two adjacent opposite side walls A of the pail, the upper or clenching ends of the anvils being in the exact point or posit on where the bail perforates the corner folds and is to be clenched.- It will be understood that these anvils thus provide for the clenching of the bail upon the inner faces or sides of the corner folds and prevent the bail from assing through or perforating the said adjacent side walls which are thus left entire, the bail passing through and being attached solely to the corner folds at the upper end thereof, where the same overlap so that the bail passes through both sets of corner folds on each side of the pail. lVhen the pail has been carried downwardly and assembled in the pail-former, and has been brought to its lowermost position in such former, the fasteners are applied and clenched in the manner hereinbefore described, and practically simultaneously the bail is applied and clenched in the manner above stated. In the clenching operation, the driving hammers 8-1 are driven inwardly by means of the angular portion of the slots 86 and in such driving or hammering operation, the extreme bent ends of the bail which are to be clenched rest against the shoulders 89 of the hammers, with the result that such bail ends are guided properly so that they will readily perforate the corner folds of the pail and strike the anvils in such a manner as to be turned over and clenched, as cl arly illustrated in Fig. 22. The pail is now completely equipped with its bail and fasteners and is d scharged or expelled from the machine as hereinbefore explained.

For the purpose of accurately timinp; the driving movement of the hammers or hammer plates, 1 provide for the adjustment of the plates 87 which are adjustable or movable longitudinally on the main frame plate 72. As shown in Fig. 16, the plate 87 are provided with depending ribs 87, which are received in corresponding channels or guideways on the upper face of the main frame plate 72. Each plate is provided with a pair of longitudinal slots 87 Figs. 3, 14 and 18, through which pass screw bolts 111, such bolts going into the main frame plate 72, whereby the plates 87 may be clamped in different adjusted positions with respect to such frame plate. As shown more clearly in Fig. 18, the rear end of the plates 87 are provided with depending flanges 87 through which pass the adjusting screws 112, which also screw into the rearward end of the main frame plate 72. By rotating the adjusting screws in one direction or the other the plates 87 are moved lon itudinall ac to TY cording to the direction of rotation of the adjusting screws, and the position of such plates with respect to the main frame plate, which is stationary. is adjusted at the will of the operator. The result of this longitudinal adjustment of the plates is to cause earlier or later action of the hammers in the forward reciprocating movement of the slide plate.

Provision is made for disassembling the parts of the machine; and in respect to the bail mechanism, 01' rather the slide plate proper, the same may be removed after the removal of a block 113 which closes the rearward end of the slide plate 7 1-. This block is in, position by means of the clamping screw 114 extending upwardly through a portion of the main frame of the machine and into said block. In like manner, the mechanism for attaching the fasteners may be removed by sliding the plates 38 and 39 outwardly as hereinbefore explained.
